Hausdorff gaps reconstructed from Luzin gaps

We consider a question: Can a given AD-family be ADR for two orthogonal uncountable towers? If $b > \omega_1$, then we rebuilt any AD-family of the cardinality $\omega_1$ onto a Hausdorff pre-gap. Moreover, if a such AD-family is a Luzin gap, then we obtain a Hausdorff gap. Under $b = \omega_1$, a similar rebuilding is impossible.Comment: 7 page

Ideals which generalize (v0)(v^0)

We consider ideals $d^0(\mathcal{V})$ which are generalizations of the ideal $(v^0)$. We formulate couterparts of Hadamard's theorem. Then, adopting the base tree theorem and applying Kulpa-Szyma\'nski Theorem, we obtain $cov(d^0(\mathcal{V}))\leq add(d^0(\mathcal{V}))^+$.Comment: A part of Kalemba's dissertation, under Plewik's supervision, is contained her

Changing the Channel: A Study of Agenda, Immersion and Social Commentary in Art

This thesis examines the concepts and ideas that pervade my body of work in painting. These concepts include immersion and scale, interactions in space, harmony and disunity, flat and dimensional space and perhaps most importantly, ambiguity. I intentionally use these formal devices to create immersive environments that appear as a familiar but skewed version of reality. By forcing together disparate languages of visual representation into the theoretical space of a painting, I strive to expose some of the humor and decay of our social institutions. In using the format of collage, my paintings have the opportunity to incorporate a wide array of iconography and imagery, while adding commentary through their juxtapositions. This thesis further explores the notion of oversaturation of images in media and how it has resulted in a clashing of imagery in the public space, akin to the format of collage in art-making. By using more easily readable or accessible iconography like cartoons or digital images to draw viewers in to the work on a visceral level, I discuss how the audience becomes witness to something sinister or something in the process of decay. Since I do not fully understand my own position as an artist and consumer of images, painting serves as a way to examine and question my relationship to society and culture as a whole. The artworks are inevitably questions in themselves: Who is to blame? What does it mean to be American? What is my duty as an artist

On some ideal related to the ideal (v0)

The ideal (v0) is known in the literature and is naturally linked to the structure [ω]ω. We consider some natural counterpart of the ideal (v0) related in an analogous way to the structure Dense(ℚ) and investigate its combinatorial properties. By the use of the notion of ideal type we prove that under CH this ideal is isomorphic to (v0)

Urban poverty and implications for social work training and practice: the Malawi scene

A workshop paper on the role of Social Work in mitigating urban poverty in Malawi.This paper assesses the role that social work can play in social development and in particular in mitigating the effects of poverty in urban areas. The paper supports the thesis that while the philosophy of social work is relevant to solving problems, its methods and training of social workers need to be made more relevant to the Third World to make an effective contribution to solving the problem of poverty. The paper therefore sees a new role for social work in the context of social development which in turn has wide-ranging implications on its methodology. Using Malawi as an example it acknowledges that this process has already begun but needs to be pursued further.Overseas Development Administration; British Development Division (Central Africa) (The British Council

"It's uncomfortable for us to be called sisters": an exploratory study into the experiences of male nurses in a Johannesburg hospital, South Africa

A Research Report submitted in partial fulfilment of a Master of Arts in Industrial Sociology by coursework and Research Report. Faculty of Humanities, University of the Witwatersrand. 15 March 2016The aim of this study is to understand the experiences of male nurses as they work in women-dominated workplace. The focus of other studies has been on: the ‘glass escalator’ and the hidden advantages for men in the so called ‘female’ professions; masculinity at work; the experiences of men in female dominated occupations and the experiences of men in caring professions. In South Africa, many studies on masculinity have been carried out that focus on the gender issues of southern Africa such as, causes and prevention of intimate partner violence; young men and the construction of masculinity, implications for HIV/AIDS, conflict, and violence; contemporary masculinities particularly the gendered cultural politics and hegemonic masculinities/masculinity in South African: culture, power and gender politics. But there is a dearth of literature on the issue of men in gender concentrated occupations, like nursing, in South Africa. This study seeks to fill the gap in understanding of how South African men experience their masculine gender identity in the context of engaging in work which is supposedly feminine by employing a qualitative, semi-structured interview approach of 15 male nurses of a hospital in Johannesburg, South Africa. This study argues that male nurses tend to portray hegemonic masculinity as their gender identity is simultaneously being configured, misconfigured and reconfigured in the workplace.MT201

Borders As Documents Of Violence: Colonial Cartography And The Epidermal Border

This dissertation analyzes the role of violence as constitutive and integral to border experiences. I focus on my lived experiences through transnational interaction with borders as analytical texts through which I realize that I am and have always been branded a Black man. I analyze the role of colonial cartography in the construction of the racialized body in Half of A Yellow Sun (2013) by relating the contrived mapping of Africa as symbolic of the mapping of race on to the black body. I also analyze the fixity of the colonial gaze in The Last King of Scotland (2006), focusing on the role of diplomatic corps in post-independence Africa, and the role of Western media in propagating and perpetuating through media representations, the divide between Africa and the West. Through autobiographical narratives, I highlight the contingency of the border in spaces marked by the white gaze. I propose the term the epidermal border as a theoretical framework to describe the bridge that links my border experiences in Uganda and the US. Conceptually, it provides a vantage point for bridging Africa and its diaspora under the shared condition of Blackness. Drawing on border rhetorics, postcolonial theory, and surveillance theory, I argue that borders are documents of violence, and that there are no borders without violence. For bodies of African descent, the epidermal border marks the permanence of violence that is always lurking in spaces marked by the white gaze. I lean heavily on the work of W.E. B Dubois, Frantz Fanon and Simone Browne, whose concepts of the color line, violence, branding, and luminosity are foundational to my thinking on Afro-diasporic bodies and border experiences

Investigation of the Yield and Composition of Essential Oils of Culinary Herbs before and after Decontamination

Herbs and spices are widely used in food industry due to the presence of nutrients and nonnutritive biologically active compounds. Their primary functions are to provide diversified taste, smell and colour to products. Additionally, spices provide preservative, nutritional and health function. Most spices owe their unique flavour character mainly to essential oil content. Essential oils that are mixtures of volatile fragrant compounds are used as natural antioxidants as well as antimicrobial agents against food-borne pathogens and food spoilage bacteria. Fresh and dried spices are contaminated by microorganisms that should be removed before introducing them to food products in order to ensure their safety and prolong shelf life. Sterilization, including steam sterilization, is the common method used for spices decontamination. The aim of the study was to evaluate the effect of steam sterilization on the amount and composition of essential oil of two common leaf spices, mint and sage

Facteurs Explicatifs De La Faible Couverture Vaccinale Chez Les Enfants De 0 à 11 Mois Dans La Zs De Luiza, Rdcongo : Risques Et Perception Des Mères.

La vaccination des enfants est devenue une activité importante du programme élargie de vaccination ayant pour  objectif principal d’assurer la couverture vaccinale de plus de 90% à tous les enfants de la RDC. Malgré les efforts effectués par le PEV ces dix dernières années, tous les indicateurs de couverture vaccinale indique une évolution en dents de scie. Plusieurs études ont tenté d’identifier les facteurs ou raisons qui sont à la base du refus et des résistances à la vaccination. Par la présente recherche : l’âge des femmes, la profession de la mère, la religion du chef de ménage,  le niveau d’instruction des femmes,  le niveau de vie des ménages ce sont révélés comme facteurs exclusifs de l’explication de la faible  couverture vaccinale.La vaccination des enfants est devenue une activité importante du programme élargie de vaccination ayant pour  objectif principal d’assurer la couverture vaccinale de plus de 90% à tous les enfants de la RDC.
